Wealthy individuals have a higher carbon fingerprint. A new study published in Nature climate change The climate results are determined by these disparities. And you find that the richest 10 % in the world are responsible for two -thirds of the noticeable global warming since 1990 and climate increases in the climate such as heat waves and islands.

The study evaluates the contribution of the highest groups emitted within societies and finds that the highest 1 % of the richest individuals in the world contributed to the global average in the average monthly temperature for 1 in 100 years in the world and 17 times more than the drought of the Amazon.

The research sheds the new light on the links between inequality in income -based emissions and climate injustice, which shows how wealthy individuals’ consumption and investments have been incompatible on harsh weather events. These effects are particularly severe in weak tropical regions such as Amazon, Southeast Asia and South Africa – all regions that have historically contributed to global emissions.

“Our study shows that severe climatic effects are not only the result of abstract global emissions, but we can instead link them directly to our lifestyle and our investment options, which in turn are related to wealth,” explains the main author Sarah Shongart, a graduate of the young Summer 2024 (YSSP) program, currently associated with the film.

Using a new framework for modeling that combines economic data and climate simulation, researchers enable the tracking of emissions from different global income groups and evaluate their contributions in the maximum specified climate. They found that emissions from the richest 10 % of individuals in the United States and China alone, each led to a two -to three times an increase in the maximum temperatures across the weak regions.

“If everyone had expelled 50 % of the world’s population, the world would have seen the minimum additional warming since 1990,” says co -author of the co -author Karl Friedrich Chliocser, who leads the integrated climatic effects of IISA. “Treating this imbalance is crucial to a fair and effective climate work.”

The study also emphasizes the importance of emissions included in financial investments, rather than personal consumption. The authors argue that targeting financial flows and high -income individuals can result in significant climatic benefits.

“This is not an academic discussion – it is related to the true effects of the climate crisis today,” he added. “Climate work that does not address the huge responsibilities of the richest members of society, is missing from missing persons from the strongest wheels we have to reduce harm in the future.”

Authors suggest that their results can stimulate the tools of progressive policy targeting social elites, noting that such policies can enhance social acceptance of climate work. Make the wealthy individual pollutants can also help providing the support that is needed for adaptation, loss and damage in weak countries.

They concluded that the balance of responsibility for climate work in line with the contributions of actual emissions is necessary, not only to slow global warming, but to achieve a more just and flexible world.
